Patented Sept. 22, 1931 warren STATES ALBERT c. BLACKBURN, orfmemso v, W sconsin DETACHABLE HEEL Application filed December 29, 1930. I Serial No. 505, 48.

This invention relates to certain new and useful improvements in shoe heels and attachments therefor.

One of the principal Objects of the inven- 15! tion consists in the provision and arrangement of an attachment of this character to permit ease in the removal and replacement of heels in an effective and expeditious manner through the employment of a simple tool.

With the above and other objects in view, the invention further consists of the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings Figure 1 is a fragmentary side elevation of a shoe heel illustrating by full and dotted lines the relative arrangement of the fasten ings therefor. I

Figure 2 is a fragmentary bottom plan view of an assembled heel.

Figure 3 is a top plan view of the heel er se. p Figure 4: is a fragmentary side elevation of a heel portion of a shoe with the attachments applied.

Figure 5 is an enlarged detail sectional view taken through the heel portion of the shoe and heel therefor showing the attachment in position to release the heel.

Figures 6 and 7 are perspective views of the component sections of the means of fastening.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates generally a shoe upper, 11 the sole therefor and 12 the heel portion; all of the above is of the usual and well known con struction and forms no part of the present application for Letters Patent but are mentioned merely for purposes of illustration in bringing forward the novel advantages of the present invention.

The invention primarily resides in the provision and arrangementof a heel 13 having elongated slotted portions 14 in communication with counter-sunk openings 15 of cross section circular formation. Disk members 16,

carried within the body of the heel, and dis- 7 posedin the manner suggested in Figures 1 and 5 of the drawings, are also provided with an elongated slotted portion 17 designed for alignment with the correspondingly shaped slots 14. Fastening elements in the nature of threaded shanks'lS passed turough the registering elongated slots l l and 17 in the heel and disks respectively, have portions upon diametrically opposite sides thereof flattened, as at 19, and in alignment with the correspondingly disposed portions 20 of the fastening head 21. Said head is slotted or otherwise provided with a kerf 22 for the 210- 1 commodation of the working extremity of a screwdriver or like instrument by means of" replaced in an effective and expeditious manner through the employment of a screw driv- The present invention overcomes the usual necessity of ripping worn heels from shoes, clipping ofl the old means of fastenings, such'as screws, nails and the like, and the sub- 7 sequent nailing ofthe new heels in position for use. The wearer of shoes equipped and constructed in the manner set forth may procure new heels by size or number and apply them himself.

The invention is susceptible of various 7 changes in its form, proportions and minor details of construction and the right is herein reserved to make such changes as properly 1 fall within the scope of the appended claims.

, Having describedthe invention, what is claimed is:

1. A detachable shoe heel construction comprising a heel body having a multiplicity of elongated slots in communication with circular-shapedcounter-sunk openings, disk members embedded within the body having slots corresponding in shape and in constant alignheel body having a multiplicity of elongated slots opening toward the upper side thereof and in communication from its under side with circular-shaped counter-sunk entrance openings, disks immovably positioned within the heel body having slots constructed after the manner of and in constant alignment with the elongated slots, and screw fastenings for the heel having the shanks therefor embedded within the shoe and the heads shaped to pass through the registering slots to underlie said disks when shifted a quarter turn. In testimony whereof Ialfix my signature.

ALBERT C. BLACKBURN.
